Google Chrome is a web browser from Google, an American company. A code execution vulnerability exists in Google Chrome prior to version 136.0.7103.59, which stems from an out-of-bounds memory access in DevTools, and can be exploited by an attacker to cause heap corruption...

The vulnerability of the Windows Routing and Remote Access Service (RRAS) on Windows operating systems allows a perpetrator to gain unauthorized access to protected information.

The vulnerability of the Windows Routing and Remote Access Service RRAS on Windows operating systems is related to reading data beyond the buffer boundaries in memory. Exploiting this vulnerability can allow a malicious actor, operating remotely, to gain unauthorized access to protected informati...

xorg: xwayland: Out-of-bounds write in CreatePointerBarrierClient()

An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching...

kernel: uprobe: avoid out-of-bounds memory access of fetching args

An out-of-bounds overflow vulnerability was found in the Linux kernel. When Uprobe needs to fetch args into a per-CPU buffer and then copy to a ring buffer, sometimes user-space strings and arrays can be very large, but the size of the per-CPU buffer is only page size and checking is not performe...

kernel: Kernel: Denial of Service in pci_endpoint_test due to zero-length DMA mapping

A flaw was found in the Linux kernel's pciendpointtest module. A local attacker with low privileges could exploit this vulnerability by providing a zero-length Direct Memory Access DMA mapping to the dmamapsingle function. This improper input validation can lead to a kernel panic, resulting in a...

kernel: RDMA/mlx5: Move events notifier registration to be after device registration

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Move events notifier registration to be after device registration Move pkey change work initialization and cleanup from device resources stage to notifier stage, since this is the stage which handles this work events...

kernel: ACPI: PAD: fix crash in exit_round_robin()

In the Linux kernel, the following vulnerability has been resolved: ACPI: PAD: fix crash in exitroundrobin The kernel occasionally crashes in cpumaskclearcpu, which is called within exitroundrobin, because when executing clearbitnr, addr with nr set to 0xffffffff, the address calculation may caus...

kernel: Secure Boot does not automatically enable kernel lockdown

The Linux Kernel lockdown mode for kernel versions starting on 6.12 and above for Fedora Linux has the lockdown mode disabled without any warning. This may allow an attacker to gain access to sensitive information such kernel memory mappings, I/O ports, BPF and kprobes. Additionally unsigned...

kernel: vmxnet3: Fix packet corruption in vmxnet3_xdp_xmit_frame

A vulnerability was found in the Linux kernel's vmxnet3 network driver in the vmxnet3xdpxmitframe function. An incorrect DMA address calculation caused by the use of a fixed rather than dynamic offset leads to a corrupt packet being sent out and subsequently dropped on the path. This can lead to...

kernel: dmaengine: idxd: Fix possible Use-After-Free in irq_process_work_list

A vulnerability was found in the Linux kernel's DMA engine component in the irqprocessworklist function. A possible use-after-free condition can occur during list iteration, which is because a descriptor may be freed while another thread is reusing it, potentially leading to access to freed memor...

Medium: libxml2

Issue Overview: In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python API Python bindings because of an incorrect return value. This occurs in xmlPythonFileRead and xmlPythonFileReadRaw because of a difference between bytes and characters...
